**Kuaishou Cyberattack Disrupts Livestreaming, Triggers Stock Decline**
On December 22, 2025, Chinese short-video platform Kuaishou Technology suffered a cyberattack targeting its livestreaming services, leading to service disruptions and exposure of users to inappropriate content. The attack, detected at approximately 10:00 p.m. local time (14:00 GMT), prompted an immediate emergency response from the company, though some functions remained partially disrupted during recovery.
Kuaishou confirmed the incident in a December 23 announcement, stating that the attack temporarily interrupted livestreaming and allowed explicit or violent content to surface. Other app services remained unaffected. The company reported the breach to authorities and is pursuing legal action against the perpetrators, condemning illegal activities linked to underground cybercrime networks.
The attack had an immediate financial impact, with Kuaishou’s Hong Kong-listed shares (HK:1024) plunging as much as 6% on December 23—the steepest single-day decline since October 14—closing at HK$62.70 ($8.06), its lowest level since November 21. The stock also led declines on the Hang Seng Tech Index, which fell 0.5% that day.
The incident follows earlier cybersecurity concerns involving Kuaishou. In September 2025, a threat actor claimed to have leaked order data allegedly stolen from the platform, including usernames, phone numbers, and addresses, after compromising a livestream room to place fraudulent orders for virtual goods.
The breach underscores the growing risks for social video and live-commerce platforms, where attacks can escalate from service disruptions to content manipulation, financial fraud, and data exposure, with lasting operational and reputational consequences.
